Resumo

Fusion 2-(4,6-dimethylpyrimidin-2-yl)-5-methyl-2Н-pyrazol-3-ol with phenols leads to the formation of complexes which exist due to a system of intermolecular N···H–O hydrogen bonds. The complexes are stable at high temperatures: their melting and subsequent thermolysis are accompanied by endothermic effects.
